METHOD OF TRACKING A POSITION OF A MAGNET BY DIFFERENTIAL MEASUREMENT

The invention is a method for tracking a position of a magnet moving relative to a magnetometer array. On the basis of the magnetic field detected by each magnetometer of the array, the position of the magnet is estimated. This estimation is based on taking into account a reference magnetic field es...

Beschreibung
Zusammenfassung:	The invention is a method for tracking a position of a magnet moving relative to a magnetometer array. On the basis of the magnetic field detected by each magnetometer of the array, the position of the magnet is estimated. This estimation is based on taking into account a reference magnetic field established beforehand, this reference magnetic field being subtracted from the magnetic field detected by each magnetometer, so as to form a differential measurement. The various successive estimations of the position of the magnet allow its path to be tracked.
